  • Patent number: 11118746
    Abstract: An electronic candle includes a housing, an electric wire extending from the upper end of the housing, a flame piece connected to the tail end of the electric wire and a control circuit arranged in the housing and electrically connected with the electric wire. At least the middle part of the upper end of the housing is formed into a concave portion, a hole is formed in the concave portion, a container for containing liquid is arranged below the hole, the opening of the container is hermetically connected with the upper end of the housing, and the hole is communicated with the inside of the container. Liquid can be contained in the concave portion to simulate molten wax water formed at the upper end of a candle body after a real candle is ignited, and the simulation degree is higher. The liquid can be a liquid containing fragrance.

  • Patent number: 10436396
    Abstract: The present invention provides an artificial candle includes a hollow cylinder, an electric wire, and a light bulb. The light bulb includes a light source with a long strip shape, a cup sleeved on and fixed to the electric wire at a position near the first end of the electric wire, an outer cover covered on the cup, and an inner cover sleeved on the light source and defining a receiving space with the cup for receiving a part of the light source and the second end of the electric wire. The light transmitted of the inner cover is less than that of the outer cover and that of the cup. The inner cover is configured for reflecting light emitted from the part, received in the receiving space, of the light source towards the wire holder and an exposed part of the electric wire. A simulating effect of flame is improved.
